Second generation VI (2009–2026) / Hyundai Equus VI 2009-2026 Service Manual / Engine Control/Fuel System / Engine Control System / Heated Oxygen Sensor (HO2S) Description and Operation
| Description |
Heated Oxygen Sensor (HO2S) consists of zirconium and alumina
and is installed both upstream and downstream of the Manifold Catalytic
Converter. The sensor output voltage varies in accordance with the
air/fuel ratio.
The sensor must be hot in order to operate normally. To keep
it hot, the sensor has a heater which is controlled by the ECM via a
duty cycle signal. When the exhaust gas temperature is lower than the
specified value, the heater warms the sensor tip.
